Abstract: PURPOSE:To lower a forward voltage drop of and to shorten a reverse recovering time of a semiconductor rectifying device by forming a P<-> type semiconductor layer on an N<+> type semiconductor layer and forming a plurality of P<+> type regions and N<+> type regions in a layer thereon. CONSTITUTION:A P<-> type semiconductor layer is formed on an N<+> type semiconductor layer 1, a plurality of regions 14 having a plurality of P<+> type semiconductor regions 13 and a plurality of regions 16 having a plurality of regions N<+> type semiconductor regions 15 are formed thereon. When a voltage of positive at the side of electrode 17 is applied between the electrodes 4 and 17, holes are injected from the side of the regions 13 to the side of the layer 2. Further, electrons are introduced from the side of the layer 1 to the side of the layer 2, and the electrodes 4 and 14 becomes conductive therebetween. When a voltage of negative at the side of the electrode 17 is applied thereto, the region 15 disposed in parallel with the region 13 absorbs electrons injected to the side of the layer 2 from the side of the layer 1 when becoming conductive therebetween. Accordingly, accumulation of electrons can be avoided in the boundary between the layer 2 and the regions 13.

Title: Method for photoresist exposure
Inventor: NISHIUCHI KAORU
IPC: H01L21/30
Filed: 1990-04-26
Abstract: PURPOSE:To obtain resist patterns of high dimensional precision with controlled exposure time by irradiating a photoresist film with nonsensitive infrared rays and by measuring variations in the ratio of intensity of infrared reflected light at the exposed zone to that at the unexposed zone. CONSTITUTION:A shutter 3 is opened for exposure by ultraviolet rays 7 emitted from a mercury-vapor lamp 1. The cross-linking of molecules of polyvinyl cinnamate advances by exposure with ultraviolet rays, so that -CH=CH- bond in the molecule disappears to vary the molecular structure. Since -CH=CH- bond has absorption characteristics to infrared rays of wavelength 5.95-6.16mum, decreases in -CH=CH- bond in the resist film with advancement of exposure causes decreases in infrared absorption of the wavelength at the exposed zone 13, increases in the intensity I of infrared reflected light, and reductions in its ratio I0/I to the intensity I0 of infrared reflected light of the wavelength at the unexposed zone 14. The ratio I0/I is measured by an infrared detector 16, and the shutter 3 is closed to end exposure at exposure time tk upon reaching the value k of I0/I in an exposure state whereby an optimum resist pattern is obtained.

Filed: 1990-04-27
Abstract: PURPOSE:To decrease the loading on a hearth by disposing a compressing member below the pulling chain extended between both bracket on the furnace side and counter-furnace side of the conventional sampler and in parallel therewith. CONSTITUTION:The compressing member 27 which receives the tension of the pulling chain 13 is disposed between both brackets 17 and 18 on the furnace side and the counter-furnace side disposed to a stand 4 below the chain 13. The sampler 1 pulling reaction F'1 generated in the counter-furnace side bracket 18 at the time of pulling of the sampler 1 is transmitted via the compressing member 12 to the furnace side bracket 17 in this way, by which the reaction reverse from the reaction generated at the time of press-fitting of the sampler 1 is generated at the furnace side supporting point of the stand 4. The counter- furnace side supporting point is sufficient with one point and the sampler 1 pulling reaction does not act either; therefore, the loading on the hearth 16 is decreased. The same effect is obtainable as well at the time of the press- fitting of the sampler 1.
